FURROW FORMER.

Application filed June 8,

This invention relates to irrigation markers and more particularly to a device for forming furrows in the surface of a field which is to be irrigated to produce irrigation channels.

An important object of the invention is to provide adevice of this character which may be Very simply and cheaply produced and which will be readily adjustable to determine the space between adjacent furrows.

A further object of the-invention is to provide a device of this character wherein the lift controlling the depth of engagement of the marking shovels is so constructed that very little force is necessary to operate the same.

These and other objects we attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein I Figure 1 is a plan view of an irrigation marker constructed in accordance with our invention;

Figure 2 is a side elevation thereof, parts being broken in section; Figure 3 is a section on Figure 1.

Referring now more particularly to the drawings, the numeral generally designates a main beam, the forward end of which is adapted to be secured to a draft andthe rear end of which has mounted thereon a seat 11. Beneath the rear end of the beam 10 extends a transverse axle 12 which is secured to the beam and to the rear ends of the horizontal flanges 13 of the angle iron bars 14 which parallel the beam, with the exception of their forward ends. At their forward ends, these angle iron bars converge upon the beam, as at 15, and are secured thereto. Mounted upon the axle 12 outwardly of the bars 14 are supporting wheels 16 which may be held in adjusted positions upon the axle by split clamping collars 17 engaging the axle. Secured to the horizontal flanges of the angle bars adjacent the forward ends thereof is a transversely extending shovel beam shaft 18, the ends of which are engaged by braces 19, the forward ends of which are secured to the converging portions of the bars 14. Between the braces 19 and the bars 14, the shaft 16 has rotatably engaged therewith the forward ends of shovel beams 20 which are held in the line 33 of from a distance equal to the distance between 1826. Serial no 114.489.

adjusted positions upon the shaft 18 by split collars 21 similar to the collars 17.

Secured to the vertical flange 22 of one of the angle bars is a segment 23 in which is axially pivoted a shaft 24 having arms 25 secured thereto and operating in planes paralleling the outer faces of the vertical flanges 22 of the angle bars. The ends of these arms are connected by links 26 with the arms 27' of an inverted U-shaped member 28 which straddles the beam 10 and bars 14, the connection to the arms of the U-shaped member being at a point adjacent the bight 30 there of. The ends of the arms of the U-shaped member have outwardly directed horizontal extensions 31 passing beneath the beams 20. These beams are longitudinally slotted, as at 32, and through the slot are directed the arms 33 of U-bolts clamping the extensions 31 to the beam. The extensions 31 are made 75 of sufficient length to permit of adjustment of the shovel beam along the shaft 18. The lower ends of i these beams have secured thereto shovels 34 of any desired construction.

Upon the beam 10 in advance of the U-shaped member 29 are secured a pair of longitudinally spaced standards 35 and 36. The standard 35 is provided adjacent its upper end with a circular opening 37 directed longitudinally of the beam, while the standard 36 is formed with a vertical slot 38, the lower end of which is arranged in the same plane as the bottom of the opening 37. The upper end of the standard 36 is formed with a V-shaped notch 39. Through the opening 37 and slot 38 is directed a shaft 40, the rear end of which is provided with a revert 41 overlying the shaft and spaced therethe bottom of the slot 38 and the bottom of the notch 39. This revert is, however, spaced from the shaft 40 a distance greater than the distance between the upper end of the slot 38 and the upper end of the standard. The end of the revert is provided with an extension 42 perpendicular to the shaft 40 with which is slidably engaged a tube 43, the outer end of which is provided with a T-head 44 pointed upon its opposite ends to provide a ground scoring implement. The forward end of the shaft 40 has secured thereto one end of a bar 45, the opposite end of which is provided with an angular extension adapted for selective engagement in alongitudinally extending series of openings 46 formed in the tube a3. The extension is of suflicient length to pass through the tube and enable the application of a nut 47 thereto, so that it will not be accidentally disengaged.

It will be seen that with a construction of this character, all of the weight which must be elevated in order to elevate the shovels is the weight of the yoke and a portion ofthe weight of the shovel beams 20 and their attached shovel. The beams and wheels may be readily adjusted upon their respective shafts. In actual operation, these wheels track the furrows formed by the shovels so as to pack the bottoms of these furrows and thus provide achannel which will not be obstructed by loose clods and which will not be readily eroded.

Since the construction hereinbefore set forth is obviously capable of acertain range of change and modification without materially departing from the spirit of the invent-ion, we do not limit ourselves to such specific structure except as hereinafter claimed.

e claim l. A device for forming irrigation char.- nels comprising, a beam, an axle arranged at the rear end'of the beam, a shaft secured to the beam in advance of the axle and extending transversely thereof, wheels adjustable upon the ends of the axle, shovel beams adjustable upon the ends of said shaft, an inverted U-shaped member straddling the beam and having at the lower ends of the arms thereof out-turned port-ions engaging the shovel beams at points spaced from said shaft and means for vertically adjusting said U-shaped member.

2. A device for forming irrigation chan nels comprising, a beam, an axle arranged at the rear end of the beam, a shaft secured to the beam in advance of the axle and extending transversely thereof, wheels adjustable upon the ends of the axle, shovel beams adjustable upon the ends of said shaft, an inverted U-shaped member straddling the eam and having at the lower ends of the arms thereof out-turned portions engaging the shovel beams at points spaced from said shaft, means for vertically adjusting said U-shaped member including a pivoted lever, a segment with which the lever coacts, a shaft rocked by the lever and having arms at opposite ends thereof and links connect ing the free ends of said arms with the arms of the U-shaped member adjacent the bight portion thereof.

3. A device for forming irrigation channels comprising a beam, an axle arranged a' the rear end of the beam, ashaft secured to the beam in advance of the axle and extending transversely thereof, wheels adjustable upon the ends of the axle, shovel beams adjustable upon the ends of said shaft, an inverted U-shaped member straddling the beam and having at the lower ends of the arms thereof out-turned portions engaging the shovel beamsat points spaced from said shaft, U-bolts straddling said out-turned portio-nsand extending through longitudinally directed slots formed in the shove beam and means for vertically adjusting said U-shaped member.

In testimony whereof we hereunto afi'ix our signatures.
